OK....the frame rail width from outside to outside is 3 3/8". The chrome bumper cover is 55" with an additional 4" on each side to reach the outside of the fenders, equaling a total of 63" outside fender to outside fender. Keep in mind the this measurement is just below the turn signals, and as you move further towards the rear of the fender it starts to flare outwards a bit, making the measurement a bit longer. Let me know if you need more specific measurements.
